Hi all;
I wonder if anyone could suggest a work-around to this little inconvenience
with the Hobo Migration Generator:
In my Instrument model, I have a self-referencing verification as follows:
class Instrument < ActiveRecord::Base
fields do
instrument_no :decimal, :default => 0, :precision => 12, :scale => 3,
:default => 0, :index => true
end
belongs_to :original_lease,
:class_name => "Instrument",
:foreign_key => :original_lease_instrument,
:primary_key => :instrument_no,
:conditions => "nature = 'LEASE'"
end
So this means when an Instrument record specifies a value for
*original_lease_instrument,* the original lease instrument pointed to must
have a nature of 'LEASE'.
However, in my application, the instrument_no field is *decimal*.
The Hobo Migration Generator keeps thinking (or assuming) that the
original_lease_instrument field is an *integer*. How do I override this?
I had to create a custom migration to reset it to decimal, but everytime I
generate a subsequent migration for anything else, Hobo wants to set it
back to an integer field:
class AddFrenchOwnershipTextToTitle < ActiveRecord::Migration
def self.up
change_column :instruments, :original_lease_instrument, :integer,
:limit => nil, :default => nil
It means I now have to edit every migration to remove that directive.
Any ideas? Where does it get this assumption from?
